protecting the heat exchanger and ensuring system safety

Look for physical bulging at the top of the aluminum case

Pressure Integrity: Maintains the internal static pressure required for proper inducer motor operation and safety switch functionality

The double pole single throw (DPST) configuration ensures robust safety by breaking the path for two separate heating elements or lines simultaneously

Key Benefits for the Contractor: Reduced Flow Resistance: The long radius 90-degree design facilitates smoother fluid transition compared to standard elbows

Amana-Goodman 20028401 Pressure Switch protecting the heat exchanger andThe Amana Goodman 20028401 Pressure Switch is a critical safety component designed for specific high efficiency furnace applications. This SPST (Single Pole Single Throw) inducer pressure switch is factory calibrated to a 1. 35" WC set point, ensuring precise monitoring of the combustion air blower's static pressure. Built for durability in demanding HVAC environments, it features a standard 1 4" barb connection for secure pneumatic tubing attachment
